I agree. PS1 and PS2 were such great systems to me because of so many great JRPG's. Many niche, some big. This generation, I find 360 getting more of the good JRPG exclusives. Tales of Vesperia, Infinite Undiscovery, Star Ocean, etc all would have been PS3 exclusives if Sony had as large of a share of Square Enix as they used to. Of course Square Enix isn't everything, but it seems to me like a lot of the games that made PS1 and PS2 what they are have been moved. This includes Wii gems like XenoBlade and Dragon Quest X, If Sony had a biiger share of SE.
For reference, I belive Sony had 40% share of Square Enix in the past, and now it's below 20%. Sony never owned Square Enix, but they owned enough to assure most exclusives came to their consoles. That's why Final Fantasy: Crystal Chronicles on GCN was a big deal.
So I think Sony should start buying shares. It's expensive, but without SE publishing a boatload of exclusives for Sony, I just can't look at the Playstation brand as it once was. Making a new studio is great too, but Sony can't let MS publish all these JRPG franchises. They gotta put more money into this.
Same with Nintendo, MS is the only developer who will really support their JRPG developers (at least they used to). Sony and Nintendo need to get back on the ball, or else JRPG's in the west will be limited to the blockbuster titles in Japan, and that's just not fair.
